All that sweat and pushing bodies, minds and souls to the limit have led to tonight, Friday Night Lights, the kick off of a new high school football season that, for some, will not end until days before Christmas.

Here’s some things we’ll be watching for as the fall unfolds:

— Will Antioch’s Najee Harris, an Alabama commit, top 3,000 yards rushing? He went for 2,744 as a junior.

— Will this be the year St. Francis finally beats Bellarmine College Prep, a skid that has reached 11 games?

— Will this be the season a Bay Area team finally beats De La Salle, a drought that stands at 25 years?

— Will Oak Grove, starting Friday night at St. Francis, continue the momentum it built last year while winning its first Central Coast Section championship in eight years?

— Which team will emerge with the championship in the new — and powerful — Diablo Athletic League’s Valley Conference, a league that includes Clayton Valley Charter, Concord, Campolindo and Miramonte?

— How will Bellarmine, which beat two Sacramento-area powers on the road (Folsom and Del Oro) while claiming a NorCal title last season, respond with much of its Speed City offense dispersed to colleges around the country?

— Will a Bishop O’Dowd team loaded with college prospects — including DB Je’Quari Godfrey and USC-bound tackle Alijah Vera-Tucker — have a huge season one year after going 7-6?

— Will this be the year Monte Vista, led by QB Jake Haener (3,005 passing yards, 35 TDs last fall), beats Foothill?

— Which team will emerge with a West Catholic Athletic League championship that Bellarmine and St. Francis shared last season?

— How will Sacred Heart Prep makeup for the graduation of two all-everything players, quarterback Mason Randall and tight end Andrew Daschbach?

— Antioch or Pittsburg? Will the Bay Valley Athletic League championship be decided when these rivals meet Nov. 5 at Antioch?
